Application filed June 16, 1913. Serial No. 773,850.

To all whamjit may concern: Be it known that 1, JO N W. Pnrrrn, a citizen of the United States, residing at San Antonio, in the county of Bexar and State of Texas, have'invented certain new and useful Improvements in Caster-Wheels, of which the following is a specification.

My invention relates to a new and useful casterroller.

The object of my invention is to pro vide a caster rollerhaving a resilient covering rigidly securedto its peripheral face, so that a piece of furniture mounted u on such rollers may be moved over polis ed floors without marring or scratching the same.

Another object is to provide a caster roller that will have a considerable portion of its underside forming a supporting surface thereby making the roller less liable to dint or mar a floor than is the case withv the ordinary roller having a very small supporting surface.

A further object is to provide a caster roller having an outer covering that will permit the direction of travel of the roller to be changed without giving rise to' much friction.

Finally the object of the invention is to provide a device of the character described, that will be strong, durable, simple and efficient, and comparatively easy to construct.

With these and various other objects in view, my invention has relatioh to certain novel features of the construction, an' ex ample of which is described in the following specification and illustrated on the accompanying drawing, wherein:

Figure 1 is a'view showing in side elevation a furniture caster provided with my Fig. 2 is an axial sectional view of the roller.

Referring now more particularly to the drawing wherein like reference characters designate similar parts inboth the figures,

the numeral 1 denotes a caster bearing adapted to be recessed in the bottom of a piano or other piece of furniture and provided with an. annular flange 2 at its lower end through which will pass screws 3 securing the bearing to the piece of furniture. In the bearing 1, there is centrally journaled a pivot pin 4, rigidly carrying at its lower end an ordinary bifurcated caster bearing 5. The pin a will preferably be headed at its upper extremity to prevent its escape from the bearing 1. Thefurcations of the member 5 support the extremities of a horizontal pin 6 upon which is mounted my novel roller.

It is to be understood that the particular type of caster frame above described is not claimed by me as new since novel roller is adapted for use in any kind of caster frame. My'roller islform'ed with an inner core 7 -which is mounted. to turn upon the pin '6 and may be formedof wood, metal or any other firm material. Upon this core is mounted fast a sleeve or bushing 8' of vulcanized rubber, entirely covering, the peripheral surface of said core. Upon the rubber sleeve or bushing 8, are wound a plurality of cloth strips 9 alternating with soft rubber strips or layers 10 having the necessary adhesive qualities hold the strips 9 in place. As the strips 9 and 10 are successively applied to the core 8, they are gradually reduced in width, so as to produce a transversely rounded surface. This surface is covered with one or two layers of a soft white fabric 11 such as felt or Wool. Thus it will be seen that none of the rubber entering into the construction of. theroller comes into contact with the surface supporting the same, so that when the direction of travel of the roller is changed, a comparatively small amount of friction will result. The outer covering 11 of the roller furthermore serves to prevent the rubber strips or layers 10 from being forced from between the stri s 9 due to any weight resting upon the rol er. The cloth strips 9 prevent the extreme outer portion of the rubber from flattening due to any weight supported by the roller. The outer covering 11 will be formed of stron and durable material that will not rea 'ly wear out. It

will be understood that the under surface all such modifications and changes as properly come Within the scope of the following claims.

What I claim is:

1. A caster roller, comprising a core a hard. rubber sleeve rigidly mounted upon the peripheral face of said core, and a coating mounted upon said sleeve, comprising one or more strips of fabric,

2. A caster roller, comprising a core, a hard rubber sleeve rigidly mounted upon the peripheral face of said core, and a coating mounted upon said sleeve comprising one or more strips of a fabric alternating with layers of soft rubber, the adhes ve quality of which serves to hold said fabric strips together.

3. A caster roller, comprising a core, a hard rubber sleeve rigidly mounted upon the peripheral face of said core, a coating amaze? mounted upon the peripheral face of the rubber sleeve comprising one or more strips of fabric, alternating with a coating of soft rubber which acts as an adhesive to hold the strips of fabric together and an outer covering of yieldable material upon the peripheral face of the roller.

4. A caster roller, comprising a core, a
